1" x 10" x RL FSC Accoya Radiata Pine Natural A1 Rough Sawn is a high-performance acetylated wood product designed for demanding exterior and architectural applications where durability, stability, and sustainability matter. Made from FSC® certified Radiata Pine, Accoya® is modified through a proprietary acetylation process that enhances the wood’s resistance to moisture, rot, swelling, and dimensional movement while maintaining the workability and natural appearance of real wood.

This 4/4" x 10" random length Accoya board is supplied in Natural A1 rough sawn grade, making it an excellent choice for exterior trim, cladding, siding, millwork, façades, soffits, windows, doors, outdoor living structures, and other applications requiring long-term performance in exposed environments. Accoya is modified through the full cross-section of the board, helping ensure consistent performance even after cutting, machining, or profiling.

Accoya offers the beauty of natural wood with enhanced stability, coating performance, and service life. It is well suited for commercial, architectural, and specification-driven projects where low maintenance, sustainability, and long-term material confidence are key requirements. Accoya is backed by an industry-leading warranty of up to 50 years above ground and 25 years in ground or freshwater contact, depending on application and installation requirements.
